Table type spectroscope --GI-STW
Gemstones selectively absorb certain wavelengths of light in the continuous spectrum to form specific absorption lines. The selective absorption is related to the structure of gemstones, that is, specific absorption lines correspond to specific gemstones. Spectroscope is a simple and very effective instrument designed to observe the spectrum of gemstones. The spectroscope is divided into grating type and prism type.
